Abstract

Abstract

Fitting threaded inserts is a common means of remedying of internal threads deterioration founded in flange of nuclear equipments, by which defective internal threads can be repaired rapidly. Moreover, the bearing capability and anti-fatigue capability can be improved. During nuclear safety reviewing on non-conformance of threads deterioration, more attention need to be paid to the conformance with standards, material of inserts, implementing program, service analysis, inspection measures and feedback in order to ensure the reliability and quality of threads remedy.
